Work Pool creation/edit not respecting required fields

[jakekaplan]

When creating a WorkPool, there can be a number of form fields that can required. The UI used to validate these fields before letting you proceed to creating a work pool.

Repro:

1. Create an AzureContainerInstance WorkPool
2. Fill in no options for the base job template (note that resource_group_name and subscription_id and required in the response from /views/aggregate-worker-metadata)
3. Observe the work pool is created successfully

Ah - this was an expected regression from #1560 but will be un-regressed (re-regressed? fixed.) with the release of this code. Given that the fix is already merged, I'm going to close this.

Thanks @znicholasbrown - if theres not a planned release of this by noon tomorrow could we get one out the door?

[znicholasbrown]

Yup 👍🏻

Just kidding, while what I said was true as well, the work pool creation wizard didn't have a validation observer on the infra creation step -this PR adds one and will close this issue properly.

Resolved by: #1570

#1570 is merged and will go out with the next release (today or tomorrow)
